failure. If you have added non-distilled water, take the vehicle
immediately to an authorized Volkswagen dealer or an author-
ized Volkswagen Service Facility to have the coolant system
drained, flushed, and refilled completely with the proper coolant.
Refill engine coolant only up to the top edge of the marked fill
range ⇒ fig. 168. Excess engine coolant may be forced out of the
engine cooling system when it gets hot and cause damage.
In the case of significant engine coolant loss, refill engine
coolant only when the engine is completely cooled down. Signif-
icant engine coolant loss is a sign of leaks in the cooling sys-
tem. Have the engine cooling system checked immediately by an
authorized Volkswagen dealer or an authorized Volkswagen Ser-
vice Facility. Otherwise the engine may be damaged!
When changing or topping off operating fluids, make sure that
you pour the fluids into the correct reservoirs. Serious malfunc-
tions and engine damage can result if you pour operating fluids
into the wrong reservoir.
